Title: Oil bath electromagnet assembly
Inventor: VIALE EDMOND AUGUST
IPC: H01F7/16
Filed: 1964-10-19
Abstract: 1,036,229. Electromagnets. DETROIT COIL CO. Oct. 19, 1964, No. 42578/64. Heading H1P. To prevent operation due solely to pressure build-up within an oil bath electromagnet assembly comprising an oil-filled sealed housing 100 containing a reciprocable plunger-type armature 122 associated with a solenoid 104, the actuating rod 132 connected to one end of the armature to reciprocate therewith and oxtending through a sealed aperture in a wall 102 of the housing is supplemented by a second rod 134 of substantially identical cross-sectional area and similarly connected to and extending through the other ends of the armature and housing; moreover, wear at the two connections is stated to be reduced by the provision thereat of lost motion. This is achieved by making apertures 150 in the rods of larger diameter than that of transverse pins 144, 146 forming the connections, and the rods are supported by bushings 136, 140 and sealed by synthetic resin gaskets 138, 142 compressed by 0-rings. A coil spring 112 biases the solenoid against the end wall 102, which has a pressure relief valve 128 which if the solenoid becomes overloaded allows oil to escape through a passageway 130.

Patent GB-1073640-A (GB)
Title: Method for preparing copolyesters
IPC: C08G63/78
Filed: 1964-10-20
Abstract: Terephthalate-isophthalate copolyesters are produced by esterifying isophthalic acid with a glycol to form a bis-glycol isophthalate having a low acid number (preferably below 10) and heating a mixture of this with a terephthalic ester and the glycol in the presence of an ester interchange catalyst to form a mixture of the glycol isophthalate and terephthalate, and then condensing this mixture to form high molecular weight linear polyesters.  The acid number of the bis-glycol isophthalate may be reduced, if necessary, by treating the ester with a solid basic material insoluble therein, e.g. sodium carbonate, or by adding material which forms an insoluble precipitate with the acid components of the ester.  The isophthalic acid may be reacted with the glycol in the presence of dialkyl terephthalate, if desired.  Suitable esterification catalysts are glycol-soluble glycolates, alkoxides, weak acid salts, tertiary amines, amphoteric metals, metals of atomic number less than 26, p-toluene sulphonic acid, acetic anhydride and sulphuric acid.  Suitable ester interchange catalysts are the acetates of lead, zinc or manganese, and litharge, and condensation catalysts may be antimony trioxide, litharge, lead acetate and glycol-soluble titanium and cobalt compounds.

Title: Apparatus for and a method of assembling workpieces
Inventor: SHUGHART MARVIN LEONARD
IPC: H01L21/50
Filed: 1970-09-07
Abstract: 1,262,237. Assembling workpieces; breaking; jointing; shearing. AMP Inc. 7 Sept., 1970 [27 Oct., 1969], No. 42721/70. Headings B3A, B3E, B3J and B3W. In a method of severing a first workpiece 2, 124 from a carrier strip 16, 126 and assembling the severed first workpiece to a second workpiece, e.g. a printed circuit board 6 or tuning knob 131 respectively, the first workpiece is severed from the strip and is carried by a punch towards the second workpiece to assemble it thereto, the carrier strip being displaced laterally of its length to allow the punch to pass the strip. Assembling terminals on circuit boards.- When a terminal 2 is located immediately beneath a punch 52, the operator places the board 6 on an anvil 120. On actuation of a switch, a compressed air cylinder 66 lowers a slide 74 so that a portion 8 of the leading terminal enters a bore 56 in the punch. A piston-rod 86 of a cylinder 88 is retracted to move a block 92 thereby shearing the terminal from the carrier strip by the action of shear edges 93, 105. Continued movement of the block 92 overcomes springs 108 to move a block 100, the carrier strip being located in a passageway 106 defined between the two blocks. When openings 96, 98 are aligned with an opening 122 in an extension plate 30, a compressed air cylinder 62 is actuated to drive the punch 52 downwardly so that a portion 12 of the terminal enters a hole 4 in the board 6. A spring loaded plunger 114 enters the portion 12 to flare it outwardly and stake the terminal to the board. Meanwhile a compressed air cylinder 48 retracts a feed finger on an arm 42 and during the return movement of the parts of the apparatus, the arm is advanced to align the next terminal with the punch. Assembling split springs on tuning knobs.- The leading spring 124 is positioned under a punch 146 by a cylinder 48, the apparatus being a modification of that shown in Fig. 1, the carrier strip 126 being engaged in a notch 176 in a slide 172. A cylinder 66, Fig. 1, is actuated to drive the punch downwardly until a guide 164 enters the spring 124 and partially enters a recess 162 after engaging the slide 172. The cylinder 88 drives the slide so as to align openings 174, 179, 181. At the same time, the carrier strip 126 is flexed and bent by virtue of an inclined side 177 of the notch 176 so that the spring 124 is severed therefrom as a nose 182 on a slide 180 urges the strip against the inclined side 177. A cylinder 62 is then actuated to drive the punch further, so that the guide 164 enters the shank 130 of the knob 131. When a pin (160) engages a block 134, 136, it pivots a lever (150) clockwise, to depress a sleeve 148 relative to the punch 146 to move the severed spring 124 over the end of the shank 130, Fig. 14 (not shown). The parts are then returned to their initial positions and the strip 125 advanced for the next work cycle.

Changes in viscosity of an elastomer sample during curing are measured by oscillating a disc 13, Fig. 3, in the sample and measuring the torque required to apply a shearing stress, using a stress transducer (not shown). During measurement the sample is contained, under constant pressure, in a rectangular chamber 4, formed between two metal die members 1, 10 of which part at least one is elastic to allow for the expansion or contraction of the sample during curing. In the embodiment, the base of the member 1 is elastic, the amount of its outward displacement being limited by a rigid backing plate 7, contacted by a boss 2 on the member 1 at the limit of displacement. The inner walls of the dies may be provided with serrated radial grooves or indentations to prevent the sample slipping over the walls. To ensure good heat transference between the backing plate 7 and chamber 4, a material, e.g. a copper spring, may be placed in the space 15.

Abstract: 1425514 Pulse monitoring circuits TOKYO SHIBAURA ELECTRIC CO Ltd 14 Sept 1973 [14 Sept 1972 21 April 1973] 43222/73 Heading H3T A logic circuit 11, 12, 13, 14 detects the start and end of an input pulse S i , Fig. 2, not shown, by comparing S i  with a delayed and inverted form thereof S 0 . The inverter 10 is clocked (CP) to effect the delay and employs complementary F.E.T.'s (Figs. 16A, 16B, 19, not shown) or F.E.T. NAND gates (Fig. 10, not shown). The NAND gate 11 (F.E.T. version, Fig. 14, not shown) detects when a positive going input edge S i  coincides with a still positive output S 0 ; and NOR gate 13 (F.E.T. version, Fig. 15, not shown) detects when a negative going edge S i  coincides with a still negative output S 0 . Two reciprocally coupled inverters 16, 17 of which one 17 is clocked out of phase with the inverter 10, perform a levelrestoring function on S 0  to correct for leakages, &c. Synchronizing the input S i  with the clock is effected Fig. 3, not shown, by two oppositelyclocked inverters 20, 21 which drive the inverter 10 and which also have level-restoring circuits 22, 25. These clocked inverters may also be complement any F.E.T. type, or they may employ Fig. 11, not shown, pairs of crosscoupled NAND gates 73A, 73B, 74A, 74B driven by clocked NAND gates 71A, 71B, 72A, 72B. The clocked NAND, NOR gates use complementary F.E.T.'s (Figs. 17A, 17B, 18A, 18B, 20, 21, not shown). To secure an output pulse (P1-P4), indicating an input pulse edge S i , which is a multiple of a complete clock period, one clocked inverter (30) and one ordinary inverter (31, Fig. 5, not shown) are included between the inverter 10 and the logic circuit 11-14. Alternatively, lengthening the output pulse may be effected by clocking the NAND, NOR gates (41, 43, Fig. 7, not shown) of the logic circuit.
